Abstract
A reactor for the continuous production of charcoal, having a substantially vertical structure, comprising, in sequence, a top charging zone, a drying zone, a carbonization zone, a cooling zone, and a discharge zone, wherein the charging zone has a smaller cross section than the drying zone and has an extension into the drying zone , forming an annular space around the extension, which space comprises, in the wall of the drying zone, an outlet to a gas extraction line for the recirculation of these gases into the reactor. The reactor reduces sawdust drag by the gases extracted from the preheating zone, without substantially altering the shape and the size of the reactor, which is achieved due to the fact that the charging zone is arranged eccentrically relatively to the drying zone, and that the outlet to the gas extraction line of the drying zone is located substantially on the larger area section of the annular space.
